Do I need to purchase a yearly update or subscription for this program. Or will it work for the next 2 years with no problem?

This Tool is Amazing, I register product as per instructions and it download all software, very easy to do. Then I proceed to check My brother SUV a Porsche Cayenne and it detected it right away but need additional software which the tool downloaded right away because it was connected to my wifi and I was able to scan all vehicle modules, it had this function to do it automatically, I am really amazed of all the trouble codes I was able to find correct and clear, now the check engine light is OFF and vehicle feels different according to my brother.
I do recommend it to every one that want a complete scan Tool.

Does this have bi- directional functions and tests?

can this model adjust tire pressure threshold in the bcm of a 2014 ram truck, and can it perform the rfhub replace function in the rfhub of that truck

Diagun iv can read the vin from all the modules?

very nice design, easy to read, good price, good vender.
